The term "Imbalance" means any gas or other hydrocarbon production, pipeline, transportation or processing Imbalance existing as of the Effective Date with respect to any of the Properties, together with any related rights or obligations as to future cash and/or gas or product balancing, as a result of, in the case of production Imbalances, Seller having taken and sold for Seller's account cumulative production which is greater or less than Seller's Working Interest share in cumulative production, or, in the case of a pipeline, transportation or processing Imbalances, Seller having delivered production which is greater or less than the production volume Seller contracted to deliver. 3.1.4 As to Wells in which Seller's Net Revenue Interest (as defined in Article 10 below) is determined to be greater than the decimal interest noted in Exhibit A, an amount determined by multiplying the Allocated Value (as hereinafter defined) for Seller's interest in the Well in question by a fraction, the numerator of which shall be the decimal increase in Seller's Net Revenue Interest in such Well from the percentage shown for such Well in Exhibit A and the denominator of which shall be the Net Revenue Interest shown for such Well on such Exhibit. 3.1.5 The value of all merchantable, clean oil and other products in tanks above the pipeline sales connection at the Effective Date that is credited to the Properties, such value to be the market or, if applicable, the contract price in effect as of the Effective Date, less any applicable leasehold burdens including royalties, overriding royalties and production payments, if any, and severance taxes. 3.2 DECREASES IN PURCHASE PRICE: The Purchase Price shall be decreased by an amount equal to the sum of the following amounts: 3.2.1 The amount of all proceeds received by Seller, net of all applicable taxes and leasehold burdens including royalties, overriding royalties and production payments, if any, attributable to production from the Properties for periods of time after the Effective Date, excluding, however, proceeds from all production prior to the Effective Date, which proceeds shall be for the account of Seller. 3.2.2 Any amounts due from Seller to other parties as of the Effective Date with respect to any Imbalances existing at the Effective Date, such amounts to be determined: (a) for production Imbalances by multiplying the Imbalance volume by $1.75 per MCF and then reducing such amount by the leasehold burdens including royalties, overriding royalties and production payments, if any, and severance taxes to be paid on such amount, and (b) for pipeline, transportation or processing Imbalances by multiplying the Imbalance volume by the price actually in effect for make-up gas if made-up prior to Closing or by $1.75 per MMBTU if not made-up and then reducing such amount by the sum of the total leasehold burdens including royalties, overriding royalties and production payments, if any, and severance and similar taxes, if any, actually paid on such amount plus the amount of all penalties and other charges on the Imbalance. 3.2.3 An amount equal to all ad valorem, property, and similar taxes and assessments based upon or measured by Seller's ownership of the Properties that are unpaid as of the Closing Date and attributable to periods of time prior to the Effective Date, which amounts shall be computed based upon such taxes and assessments for the calendar year 1997; provided that if such taxes or assessments are assessed on other than a calendar year basis, for the tax related year last ended. 3.2.4 Any amount determined in connection with uncured Title Defects as provided for in Article 10 below. 3.2.5 Any amount determined in connection with Adverse Environmental Conditions as provided for in Article 19 below. 3.2.6 Any amount determined in connection with Material Change in Condition as provided for in Section 10.5 below. 4.

There shall not exist at Closing any uncured Title Defects which exceed the Title Basket Value (as defined in Section 10.3.2(b) below) unless adjustments therefor have been made pursuant to the further terms of this Agreement or Buyer has elected to waive any such Title Defects. Buyer shall notify Seller in writing of any claimed Title Defects not less than five (5) business days prior to Closing (Title Defects Notice). The Title Defects Notice shall (a) set forth in reasonable detail the Well and/or Lease with respect to which a claimed Title Defect is made, (b) the nature of such claimed Title Defect, and (c) Buyer's proposed calculation of the Defect Value of each claimed Title Defect. Any Title Defect that is not identified in the Title Defects Notice shall thereafter be deemed a Permitted Encumbrance and be forever waived and expressly assumed by Buyer. As used in this Agreement, the term: 10.1.1 "Title Defect" shall mean, with respect to Seller's interest in each of the Wells, any lien, mortgage, pledge, claim, charge, option, defect, requirement for consent to assignment and other encumbrance which would apply to the transaction contemplated hereby, other than Permitted Encumbrances, or entitle the owner thereof to receive a percentage of all proceeds of production therefrom less than the Net Revenue Interest of Seller set forth on Exhibit A for such Well or cause Buyer to bear a greater Working Interest than set forth on Exhibit A for such well without a proportionate increase in the Net Revenue Interest therefore. For purposes of this Agreement, in evaluating the significance of a fact, circumstance or condition to determine whether the same constitutes a Title Defect, due consideration shall be given to the length of time that the particular Property has been producing hydrocarbon substances and whether such fact, circumstance or condition is of the type expected to be encountered in the area involved and is usual and customarily acceptable to reasonable and prudent operators, interest owners, and purchasers engaged in the business of the ownership, development and operation of oil and gas properties. 10.1.2 "Net Revenue Interest" shall mean Seller's interest in and to all production of oil, gas and other minerals saved, produced and sold from any Well after giving effect to all valid lessor's royalties, overriding royalties, production payments, carried interests, liens and other encumbrances or charges against production therefrom. 10.1.3 "Working Interest" shall mean, with respect to the Wells, Seller's interest in and to the full and entire leasehold estate created under and by virtue of the Leases and all rights and obligations of every kind and character appurtenant thereto or arising therefrom, without regard to any valid lessor's royalty, overriding royalties, production payments, carried interests, liens, or other encumbrances or charges against production therefrom insofar as such interest in said leasehold estate is burdened with the obligation to bear and pay costs of operations. 10.1.4 "Permitted Encumbrances" shall mean: (a) Lessors' royalties, overriding royalties, reversionary interests and similar burdens if the net cumulative effect of the burdens does not operate to reduce the interest of Seller with respect to all oil and gas produced from any Well below the Net Revenue Interest for such Well set forth in Exhibit A; (b) Division orders and sales contracts terminable without penalty upon no more than 90 days notice to the purchaser; (c) All preferential rights to purchase and required third party consents to assignment and similar agreements with respect to which waivers or consents are obtained from the appropriate parties, or which are disclosed on Exhibit D hereto.; (d) Materialman's, mechanic's, repairman's, employee's, contractor's, operator's, tax, and other similar liens or charges arising in the ordinary course of business for obligations that are not delinquent or that will be paid and discharged in the ordinary course of business or if delinquent, that are being contested in good faith by appropriate action of which Buyer is notified in writing before Closing; (e) All rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with the sale or conveyance of oil and gas leases or interests therein if they are routinely obtained subsequent to the sale or conveyance; (f) Easements, rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations that do not materially interfere with the oil and gas operations to be conducted on any Well or Lease; (g) All operating agreements, unit agreements, unit operating agreements, pooling agreements and pooling designations affecting the Properties that are either of record in Seller's chain of title or reflected or referenced in Seller's files; (h) Conventional rights of reassignment prior to release or surrender requiring notice to the holders of the rights; (i) All rights reserved to or vested in any governmental, statutory or public authority to control or regulate any of the Properties in any manner, and all applicable laws, rules and orders of governmental authority; (j) The terms and conditions of the Leases, and of all agreements that are of record in Seller's chain of title or reflected or referenced in Seller's files; (k) All other liens, charges, encumbrances, contracts, agreements, instruments, obligations, defects and irregularities affecting the Properties which individually or in the aggregate are not such as to interfere materially with the operation, value or use of any of the Properties, do not prevent Buyer from receiving the proceeds of production from any of the Wells, do not reduce the interest of Seller with respect to all oil and gas produced from any Well below the Net Revenue Interest set forth in Exhibit A for such Well, and/or do not materially increase the portion of the costs and expenses relating to any Well that Seller is obligated to pay above the Working Interest set forth in Exhibit A for such Well; (l) Any Title Defect relating to a Well that has existed for a period of at least four years immediately prior to the Effective Date (simply by virtue of its existence and not upon the occurrence of a certain event) giving a third party the right to take any action or assert any claim that could affect Seller's right to receive income or revenues from the Well to which such defect relates, and with respect to which Seller has been receiving income from the affected Well without contest or under notice of adverse claim for a period of at least four years immediately prior to the Effective Date; and (m) Any Title Defects Buyer may have expressly waived in writing or which are deemed to have become Permitted Encumbrances under Section 10.1. 10.1.5 "Defect Value" shall mean the amount by which the Allocated Value of any Well is reduced as a result of each Title Defect which is accepted by Seller or determined to be a Title Defect pursuant to Section 10.2. 10.1.6 "Allocated Value" shall mean, with respect to any Well, the value specified therefor on Exhibit A attached hereto. 10.2 DETERMINATION OF TITLE DEFECTS AND DEFECT VALUES. Within five (5) business days after Seller's receipt of the Title Defects Notice, Seller shall notify Buyer whether Seller agrees with Buyer's claimed Title Defects and/or the proposed Defect Values therefor (Seller's Response). If Seller does not agree with any claimed Title Defect and/or the proposed Defect Value therefor, then the parties shall enter into good faith negotiations and shall attempt to agree on such matters. If the parties cannot reach agreement concerning either the existence of a Title Defect or a Defect Value within ten (10) business days after Buyer's receipt of Seller's Response, upon either party's request, the parties shall mutually agree on and employ an attorney experienced in title examination in the state where the Properties are located ("Title Consultant") to resolve all points of disagreement relating to Title Defects and Defect Values; provided, however, that if at any time the Title Consultant so chosen fails or refuses to perform hereunder, a new Title Consultant shall be chosen by the parties. The cost of any such Title Consultant shall be borne 50% by Seller and 50% by Buyer. Each party shall present a written statement of its position on the Title Defect and/or Defect Value in question to the Title Consultant within five (5) business days after the Title Consultant is selected, and the Title Consultant shall make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within ten (10) business days of receipt of such position statements. The determination by the Title Consultant shall be conclusive and binding on the parties, and shall be enforceable against any party in any court of competent jurisdiction. If necessary, the Closing Date shall be deferred only as to those Properties affected by any unresolved disputes regarding the existence of a Title Defect and/or the Defect Value until the consultant has made a determination of the disputed issues with respect thereto and all subsequent dates and required activities with respect to any such Properties having reference to the Closing Date shall be correspondingly deferred; provided, however, that, unless Seller and Buyer mutually agree to the contrary, the Closing Date shall not be deferred in any event for more than sixty (60) days beyond the original Closing Date. All Properties as to which no such dispute(s) exist shall be conveyed to Buyer subject to the terms of this Agreement at Closing. Once the Title Consultant's determination has been expressed to both parties, Seller shall have five (5) business days in which to advise Buyer in writing which of the options available to Seller under Section 10.3 below Seller elects regarding each of the Properties as to which the Title Consultant has made a determination. 10.3 REMEDIES FOR TITLE DEFECT. Seller shall have the right, but not the obligation, to cure any Title Defect accepted by Seller or determined to be a Title Defect pursuant to Section 10.2 above. With respect to any Title Defect that Seller elects not to cure or that Seller fails to cure at or prior to the Closing, Seller shall have the option to: 10.3.1 (a) Exclude the Property including pipelines and other personal property necessary to operate the particular well(s) subject to the Title Defect from this Agreement, in which event the Purchase Price shall be reduced by the Allocated Value of such Property and the calculations under 10.3.2 and 10.3.3 shall not include the Allocated Value for such excluded Property, or (b) Sell the Property subject to such Title Defect to Buyer and the Purchase Price shall be reduced by the Defect Value for such Title Defect. 10.3.2 No downward adjustment of the Purchase Price on account of Title Defects shall occur unless: (a) the Defect Value determined in accordance with this Article 10 of an individual Title Defect exceeds $2,500.00, and (b) the aggregate amount of the Defect Values determined in accordance with this Article 10 exceeds $250,000 (Title Basket Value). 10.3.3 The amount of any such downward adjustment shall be the difference between the aggregate amount of Defect Values and the Title Basket Value. Should the aggregate Defect Values and/or the Allocated Values of excluded Properties exceed ten percent (10%) of the Purchase Price, then Seller shall have the option to terminate this Agreement, in which case neither party shall have any further liability or obligation to the other hereunder except as regards obligations imposed by any confidentiality agreement, which shall survive such termination and be enforceable in accordance with the terms thereof, and Seller will promptly refund the Performance Deposit. 10.4 PREFERENTIAL PURCHASE RIGHTS AND CONSENTS TO ASSIGN. Seller shall make a good faith effort to insure that all preferential purchase rights and consents to assign arising in connection with the assignment of the Properties to Buyer shall have been waived or obtained or shall have expired before or by the time of Closing; except those which are customarily obtained or received after Closing; provided, however, that if notice of the transaction contemplated herein has been given to a party or parties entitled to a preferential purchase right with respect thereto, but the time during which any such party or parties has to exercise such right has not expired, such shall not be considered as a Title Defect and the Property or Properties subject to such right shall be conveyed to Buyer at the Closing. In the event that any such preferential purchase right is timely exercised, Seller shall notify Buyer thereof, whereupon Buyer shall assign the Property or Properties affected thereby to the party or parties exercising such preferential purchase right with the consideration therefor to be paid directly to Buyer. 10.5 MATERIAL CHANGE IN CONDITION. Seller shall notify Buyer (i) as to any well that was producing at the Effective Date that ceases to produce prior to Closing and there is no reasonable expectation by Seller that such well will produce in the future or (ii) a well or field is required to be shut in for a period in excess of 180 days due to a violation of any regulation or governmental ruling. Such notice shall be in writing and delivered in a reasonable period of time after Seller has actual knowledge of either (i) or (ii) above. The value (as applied to either (i) or (ii), hereinafter referred to as "Change Value") to be attributable to (i) above, shall be the allocated value for such well, or in the case of (ii) above, the total of the allocated values for all wells affected. The allocated value for each well shall be provided by Buyer to Seller at the execution of this Agreement. As to any well or field that qualifies as a Material Change in Condition, Seller will have the option of retaining such well or field and the Purchase Price shall be reduced by the allocated value therefore. No downward adjustment of the Purchase Price on account of a Material Change in Condition shall occur unless: (a) the Change Value determined in accordance with this Article 10.5 of an individual Change Value exceeds $2,500.00, and (b) the aggregate amount of all Change Values determined in accordance with this Article 10.5 exceeds $250,000 ("Change Basket Value"). The amount of any such downward adjustment shall be the difference between the aggregate amount of Change Value and the Change Basket Value. Should the aggregate Change Value and/or the Allocated Value of excluded Properties exceed ten percent (10%) of the Purchase Price, then either party shall have the option to terminate this Agreement, in which case neither party shall have any further liability or obligation to the other hereunder except as regards obligations imposed by any confidentiality agreement, which shall survive such termination and be enforceable in accordance with the terms thereof, and Seller will promptly refund the Performance Deposit. 11. SUSPENSE FUNDS HELD BY SELLER. Seller agrees to convey and Buyer agrees to receive all suspense funds held by Seller as of the Effective Date for the benefit of royalty, overriding royalty interest and working interest owners attributable to the Properties, the amount of such funds to be adjusted with respect to suspense funds received and disbursed by Seller from and after the Effective Date, and Buyer shall assume all past, present and future liability associated with such funds, but only as to the suspense funds actually transferred, and not to any liability resulting from Seller's failure to pay or retain any amounts prior to the Effective Date in addition to the suspense funds so transferred. All past, present and future liability associated with such funds shall be assumed by Buyer and Buyer agrees to protect, defend, indemnify and hold Seller and its employees harmless from and against any and all costs, expenses, claims, demands, and causes of action of every kind and character (including attorneys' fees and court costs) arising out of, incident to, or in connection therewith. 12. CLOSING. 12.1 THE CLOSING.

Seller shall provide Buyer a closing statement reflecting the Preliminary Amount at least two (2) business days prior to the Closing. 12.2.3 Seller and Buyer shall execute, acknowledge and deliver division orders, transfer orders or letters in lieu thereof directing all purchasers of production from the Properties to make payment of proceeds attributable to such production occurring on or after the Effective Date to Buyer. 12.2.4 As to those Properties operated by Seller, Seller and Buyer shall execute all appropriate state or local forms required to be executed to effect the administrative change of operator of such Properties from Seller to Buyer, and Seller shall file such forms within five (5) business days after Closing.

Buyer shall have forty-five (45) days after receipt of the Final Settlement Statement to review such statement and to provide written notice to Seller of Buyer's objection to any item on the statement. Buyer's notice shall clearly identify the item(s) objected to and the reasons and support for the objection(s).

LIMITATION OF WARRANTIES. Anything in this Agreement to the contrary notwithstanding, the Properties are being sold by Seller to Buyer without recourse, covenant, or warranty of any kind, express, implied, or statutory, except as to title which shall pass with a special warranty restricted to by through or under Seller only, WITHOUT LIMITATION OF THE GENERALITY OF THE IMMEDIATELY PRECEDING SENTENCE, SELLER CONVEYS THE PROPERTIES AS-IS, WHERE-IS AND WITH ALL FAULTS AND EXPRESSLY DISCLAIMS AND NEGATES: (a) ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, (b) ANY IMPLIED OR EXPRESS WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, AND (c) ANY IMPLIED OR EXPRESS WARRANTY OF CONFORMITY TO MODELS OR SAMPLES OF MATERIALS.

THE REPRESENTATIONS AND WARRANTIES MADE BY SELLER AND BUYER IN ARTICLES 4 AND 5 SHALL NOT SURVIVE CLOSING. AFTER CLOSING, NEITHER PARTY SHALL HAVE ANY RIGHTS OR CLAIMS AGAINST THE OTHER PARTY BASED UPON THE BREACH OF ANY SUCH REPRESENTATIONS OR WARRANTIES. 16. CROSS-INDEMNIFICATION. Except as expressly limited elsewhere in this Agreement: 16.1 Buyer agrees to indemnify and hold Seller harmless from and against any and all liability, loss, cost and expense (including, without limitation, court costs and reasonable attorneys' fees) that are attributable to the Properties conveyed to Buyer and are attributable to periods of time on or after the Closing Date or that are attributable to a breach by Buyer of any of its surviving representations, warranties or covenants hereunder, and 16.2 Seller agrees to indemnify and hold Buyer harmless from and against any and all liability, loss, cost and expense (including, without limitation, court costs and reasonable attorneys' fees) that are attributable to the Properties conveyed to Buyer and are attributable to periods of time before the Closing Date or that are attributable to a breach by Seller of any of its surviving representations, warranties or covenants hereunder. 17.

Provided however, if on such date there exist a good faith dispute as to a material title matter or material environmental condition, or the value claimed in relation thereto, then such date shall be extended to November 30, 1998 to allow the parties time to try and resolve such dispute. 18.3 SOLE REMEDY OF BUYER PRIOR TO CLOSING. If at any time prior to Closing, a material representation or warranty made herein by Seller is incorrect or if Seller fails to fully and timely comply with any of Seller's obligations as set forth herein or as required by applicable law, Buyer's sole and exclusive remedy against Seller shall be to terminate this Agreement (unless an alternative remedy shall be mutually agreed upon between Buyer and Seller); provided, however, if such a breach consists of Seller intentionally refusing to execute and deliver the documents referred to in Section 12.2, Buyer may seek injunctive relief requiring Seller to execute and deliver such documents in accordance with the terms of this Agreement. In the event this Agreement is terminated in accordance with this Section 18.3, Seller will promptly refund the Performance Deposit. 19. ENVIRONMENTAL MATTERS 19.1 PRESENCE OF WASTES, NORM, HAZARDOUS SUBSTANCES, AND ASBESTOS. Buyer acknowledges that the Properties have been used to explore for, develop and produce oil and gas, and that spills of wastes, crude oil, produced water, hazardous substances, and other materials may have occurred thereon. Additionally, the Properties, including production equipment, may contain asbestos, hazardous substances, or Naturally Occurring Radioactive Material ("NORM"). NORM may affix or attach itself to the inside of wells, materials, and equipment as scale or in other forms, and NORM-containing material may have been buried or otherwise disposed of on the Properties. Special procedures may be required for remediating, removing, transporting, and disposing of asbestos, NORM, hazardous substances, and other materials from the Property, and Buyer assumes all liability for the assessment, remediation, removal, transportation, and disposal of these materials and associated activities in accordance with the applicable rules, regulations, and requirements of governmental agencies. 19.2 ADVERSE ENVIRONMENTAL CONDITION. As used in the following Sections, "Adverse Environmental Condition" means: (a) any contamination (exclusive of NORM present in or on any Property) or condition exceeding currently-allowed regulatory limits and not otherwise permanently authorized by permit or law, resulting from any discharge, release, disposal, production, storage, treatment, or any other activities on, in or from any Property, or the migration or transportation from other lands to any Property, prior to the Closing Date, of any wastes, pollutants, contaminants, hazardous materials or other materials or substances subject to regulation relating to the protection of the environment, including, but not limited to, the Clean Air Act, the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), the Federal Water Pollution Control Act, the Safe Drinking Water Act, the Toxic Substance Control Act, the Hazardous and Solid Waste Amendments Act of 1984, the Superfund Amendments and Reauthorization Act of 1986, the Hazardous Materials Transportation Act, the Clean Water Act, the National Environmental Policy Act, the Endangered Species Act, the Fish and Wildlife Coordination Act, the National Historic Preservation Act, and the Oil Pollution Act of 1990, as well as any state and local regulation or law governing the same, similar or related matters, and (b) any such contamination or condition temporarily authorized by permit, fee agreement or other arrangement. 19.3 ENVIRONMENTAL ASSESSMENT. After the execution of this Agreement, Buyer shall have the opportunity to conduct at its sole risk and expense an environmental assessment of the Properties. Seller will provide reasonable access for this purpose to Properties operated by Seller; for any Property not operated by Seller, however, Buyer must contact the operator of any such non-operated Property directly. Buyer or any of its representatives and agents must comply with Seller's environmental and safety rules and policies while on Seller's Properties. Buyer agrees it will not disclose any information obtained in its environmental assessment to third parties unless agreed to in writing by Seller or unless such disclosure is expressly required by applicable law or regulation or is compelled pursuant to legal process of any court or governmental authority. Buyer will notify Seller in advance of any such disclosure and will furnish Seller copies of all materials to be disclosed prior to any disclosure thereof to third parties. As soon as possible after Buyer's receipt thereof, Buyer shall forward to Seller copies of all reports, data, analyses, test results, remediation cost estimates, and recommended remediation procedures or other information concerning or derived from Buyer's environmental assessment. 19.4 NOTICE OF ADVERSE ENVIRONMENTAL CONDITIONS. Buyer shall notify Seller in writing of any claimed Adverse Environmental Condition not less than five (5) business days prior to Closing ("Environmental Defects Notice"). The Environmental Defects Notice shall (a) set forth in reasonable detail the Well and/or Lease with respect to which a claimed Adverse Environmental Condition is made, (b) the nature of such claimed Adverse Environmental Condition, and (c) Buyer's proposed calculation of the cost to remediate each claimed Adverse Environmental Condition ("Remediation Value") Buyer shall absolutely and forever waive its right to assert any claim or liability against Seller arising out of or in any way related to any Adverse Environmental Condition not set forth in the Environmental Defects Notice. 19.5 DETERMINATION OF ADVERSE ENVIRONMENTAL CONDITIONS AND REMEDIATION VALUES. Within five (5) business days after Seller's receipt of the Environmental Defects Notice, Seller shall notify Buyer whether Seller agrees with Buyer's claimed Adverse Environmental Conditions and/or the Remediation Value (Seller's Environmental Response). If Seller does not agree with any claimed Adverse Environmental Condition and/or the Remediation Value, then the parties shall enter into good faith negotiations and shall attempt to agree on such matters. If the parties cannot reach agreement concerning either the existence of an Adverse Environmental Condition or the Remediation Value within ten (10) business days after Buyer's receipt of Seller's Environmental Response, upon either party's request, the parties shall mutually agree on a consultant experienced in environmental matters in the state where the Properties are located ("Environmental Consultant") to resolve all points of disagreement with respect to such matters. If at any time any Environmental Consultant so chosen fails or refuses to perform hereunder, a new Environmental Consultant shall be chosen by the parties. The cost of any such consultant shall be borne 50% by Seller and 50% by Buyer. Each party shall present a written statement of its position on the Adverse Environmental Condition and/or the Remediation Value in question to the consultant within five (5) business days after the Environmental Consultant is selected, and the Environmental Consultant shall make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within ten (10) business days of receipt of such position statements. The determination by the Environmental Consultant shall be conclusive and binding on the parties, and shall be enforceable against any party in any court of competent jurisdiction. If necessary, the Closing Date shall be deferred only as to those Properties affected by any unresolved disputes regarding the existence of a Adverse Environmental Condition and/or the Remediation Value until the Environmental Consultant has made a determination of the disputed issues with respect thereto and all subsequent dates and required activities with respect to any such Properties having reference to the Closing Date shall be correspondingly deferred; provided, however, that, unless Seller and Buyer mutually agree to the contrary, the Closing Date shall not be deferred in any event for more than sixty (60) days beyond the original Closing Date. All Properties as to which no such dispute(s) exist shall be conveyed to Buyer subject to the terms of this Agreement at Closing. Once the Environmental Consultant's determination has been expressed to both parties, Seller shall have five (5) business days in which to advise Buyer in writing which of the options available to Seller under Section 19.6 below Seller elects regarding each of the Properties as to which the consultant has made a determination. 19.6 REMEDIES FOR ADVERSE ENVIRONMENTAL CONDITIONS. 19.6.1 As to any Adverse Environmental Condition accepted by Seller or determined to be an Adverse Environmental Condition, Seller shall have the election to: (a) remediate such Adverse Environmental Condition at Seller's sole cost in accordance with applicable environmental laws, and there shall be no adjustment to the Purchase Price in respect of such Adverse Environmental Condition and the provisions of Section 19.7 shall thereafter apply in all respects; (b) reduce the Purchase Price by the applicable Remediation Value, which in no event shall exceed the Allocated Value of the Unit and/or Well affected by such Adverse Environmental Condition, in which event Seller shall have no other or further obligation or liability in respect of such Adverse Environmental Condition and the provisions of Section 19.7 shall thereafter apply in all respects; or (c) delete from this Agreement the Property which contains the Adverse Environmental Condition and adjust the Purchase Price by the Allocated Value of such Property. 19.6.2 No downward adjustment of the Purchase Price on account of Adverse Environmental Conditions shall occur unless: (a) the Remediation Value determined in accordance with this Article 19 of an individual Adverse Environmental Condition exceeds $2,500.00, and (b) unless the aggregate sum of all Remediation Values exceeds $250,000 (Environmental Basket Value), and the amount of downward adjustment shall be the difference between the aggregate sum of all Remediation Values and the Environmental Basket Value. Should the aggregate sum of the Remediation Values exceed ten percent (10%) of the Purchase Price, then Seller shall have the option to terminate this Agreement, in which case neither party shall have any further liability or obligation to the other hereunder except as regards obligations imposed by any confidentiality agreement, which shall survive such termination and be enforceable in accordance with the terms thereof, and Seller will promptly refund the Performance Deposit. 19.6.3 If Seller elects 19.6.1(a) above, Seller will exercise all reasonable efforts and diligence to complete the remediation work within six (6) months of the Closing Date, but any failure by Seller to complete such remediation efforts by such time shall not relieve Seller of its duty to satisfy its obligation hereunder. Buyer shall allow Seller and its agents and representatives such access to the Properties as is reasonably necessary for performance of remediation work. Seller will conduct such work so as not to unreasonably interfere with Buyer's operations. 19.7 BUYER'S INDEMNIFICATION OF ADVERSE ENVIRONMENTAL CONDITIONS. Notwithstanding anything contained in Article 16, except for the costs associated with Seller's remediation of any Adverse Environmental Conditions pursuant to Section 19.6.1(a) above, Buyer shall release, defend, indemnify, and hold harmless Seller from and against any and all claims, demands, fines/penalties, causes of action, liabilities and obligations, and all costs and expenses (including, without limitation, reasonable attorneys' fees and court costs) associated with all Adverse Environmental Conditions, including, without limitation, any such conditions arising out of or relating to any discharge, release, disposal, production, storage, treatment or any activities on, in or from the Properties, or the migration or transportation from any other lands to the Properties, whether before or after the Effective Date, of materials or substances that are at present, or become in the future, subject to regulation under federal, state or local laws or regulations, whether such laws or regulations now exist or are hereafter enacted, INCLUDING, WITHOUT LIMITATION, ANY CLAIMS, DEMANDS, CAUSES OF ACTION, LIABILITIES, OR OBLIGATIONS ARISING IN WHOLE OR IN PART FROM THE SOLE OR CONCURRENT NEGLIGENCE OR STRICT LIABILITY OF SELLER. BUYER HEREBY RELEASES SELLER FROM AND AGAINST ANY AND ALL CLAIMS FOR CONTRIBUTION UNDER CERCLA AND/OR ANY OTHER ENVIRONMENTAL LAW OR REGULATION. 20. SELLER'S ELECTION TO EFFECT IRC SECTION 1031 EXCHANGE. In the event Seller so elects, Buyer agrees to accommodate Seller in effecting a tax-deferred exchange under Internal Revenue Code Section 1031, as amended. Seller shall have the right to elect this tax-deferred exchange at any time prior to the date of Closing. If Seller elects to effect a tax deferred exchange, Buyer agrees to execute additional escrow instructions, documents, agreements, or instruments to effect the exchange, provided that Buyer shall incur no additional costs, expenses, fees or liabilities as a result of or connected with the exchange. 21. FURTHER ASSURANCES. After the Closing, Seller and Buyer shall execute, acknowledge and deliver, or cause to be executed, acknowledged and delivered, such instruments and take such other action as may be reasonably necessary or advisable to carry out their obligations under this Agreement and under any exhibit, document, certificate or other instrument delivered pursuant hereto. Seller shall use its best efforts to obtain all approvals and consents required by or necessary for the transactions contemplated by this Agreement that are customarily obtained after Closing, provided that Seller shall not be required to expend any funds to obtain such approvals and consents. 22.

For a period of six (6) years after the date of Closing, Buyer will retain the Data delivered to it pursuant hereto and will make such Data available to Seller upon reasonable notice at Buyer's headquarters at reasonable times and during office hours. Buyer shall notify Seller in writing within thirty (30) days of the sale to a third party of all or any part of the Properties which involves the transfer of any of the Data of the name and address of the buyer(s) in any such sale. Buyer shall require as part of any such sales transaction that such third party assume the obligations imposed on Buyer in this Article 22. 23. USE OF SONAT NAME.
